how many adult women actually take the images in fashion magazines — artificial as they are, feats of makeup and lighting and camera angles, even without retouching — at face value? “Our readers are not idiots,” Christine Leiritz, editor of French Marie Claire, told the New York Times last year, “especially when they see those celebrities who are 50 and look 23.” Most of us who read fashion magazines don’t feel we’re confronting reality when we see a photograph of a grown woman with preteen thighs. (We certainly see enough countervailing tabloid shots to know exactly what celebrity thighs look like.) If such photos enrage us, and often they do, it’s not because they damage our self-esteem, nor — let’s be honest — because we’re constantly fretting, like some earnest psychologist or crusading politician, about the emotional repercussions for adolescent girls. Our interest in altered images is not purely moral; it’s also aesthetic. We believe that a picture should convey, “objectively,” without undue intervention, what the lens originally captured. But these days, come to a fashion, consumer, or celebrity magazine with this quaint puritanical notion in mind, and you’re bound to be disappointed: Many contemporary images are illustrations masquerading as photographs, cartoons composed with a computer rather than a pen.
